Research confirms association between African-American ethnicity, long-term alcohol dependence, and increased risk for infectious diseases. African-American alcoholics show greatest decline in natural-killer cell activity, indicating compromised immune system.
A study published in Alcoholism: Clinical & Experimental Research found that beta-endorphin levels are heritable and can predict an individual's risk of developing alcoholism. The research suggests that the hormone may be used as a biomarker to identify specific individuals at high genetic risk.
A recent study found that nicotine increases alcohol consumption and may require simultaneous treatment for addiction. Nicotine activates the brain's nicotinic receptors, leading to dopamine release, similar to alcohol consumption.
According to a NIH/NIAAA study, approximately 28.6% of U.S. children are exposed to familial alcohol dependence or abuse before age 18. Children of alcoholics face increased risk of psychopathology and medical problems, including an increased risk for developing alcohol abuse or alcoholism.
A recent study found that younger people are both drinking and developing alcohol problems at an earlier age. Those who develop alcoholism early in life have greater social and legal problems. The study also showed a strong association between early use of substances and later-in-life alcohol-use disorders, depression, and multiple hea...
Researchers in Taiwan discovered a rare individual with two copies of the genetic mutation that protects against alcoholism. This finding challenges the long-held assumption that individuals with this mutation are immune to developing alcohol disorders.
Researchers found that chronic alcohol abuse in late adulthood damages Purkinje neurons by reducing message traffic between neurons, but the damage is mostly reversible. The study also suggests a connection between alcohol-induced brain changes and abnormal movements seen in alcoholics, such as unsteady gait and tremors.
A new study from Washington University in St. Louis reveals a clear tendency among college students to become addicted to more than one common substance or activity, with exercise yielding the highest level of addiction and strong connections between certain activities and self-esteem. The study found large correlations within and betw...
Researchers found that alcohol sensitizes dopamine and serotonin neurons, leading to excitotoxicity and neuronal damage. Brain-derived neurotrophic factor (BDNF) may protect against this excitotoxicity, suggesting a potential treatment for alcoholics undergoing withdrawal.
A recent study found that the majority of Americans with alcoholism do not receive treatment, highlighting a significant gap in care. The research identified distinct characteristics among those who did receive treatment, suggesting that treatment options may need to be tailored to address specific needs.
Heavy drinking depletes dopamine, gamma aminobutyric acid, opioid peptides and serotonin systems, while promoting stress chemicals like corticotropin releasing factor (CRF). This imbalance leaves alcoholics vulnerable to relapse after stopping drinking.
A symposium on treating drug addiction will feature four new studies on the chemistry of addictions, including an antibody-based drug to prevent PCP abuse and a non-addictive medication for cocaine addicts. The research aims to understand the brain chemistry behind addiction and develop effective treatments.
